Good Sunday afternoon to you. Our forecast is right on target today… with 3pm temperatures well into the mid and upper 80s and heat indices for some in the 90s.
Right on cue with the daytime heating we’ve seen isolated heavy showers and occasional rumbles of thunder developing. The focus has primarily been around Columbus, Hope and Greensburg. But an outflow boundary (rain cooled from the storms) is lifting northward into central Johnson and Shelby counties and will likely trigger new cell development farther north.
But as mentioned earlier these only be isolated and most won’t see a drop of rain today. However if you’re under these pulse cells the rain will be torrential at times and dampen pool side plans for a bit until they rain themselves out.
This sun-driven precipitation appropriately diminishes after dark and a quiet, but muggy night is expected. Areas of locally dense for are likely Monday morning and especially in areas that see rain today.
A new round of isolated to scattered storms are on the docket during daytime heating Monday… when highs near 90 degrees in many cities with heat indices in the upper 90s.
Some of the storms will be locally strong if not producing severe wind gusts. Stay weather aware both Monday and Tuesday which will be stormy and at times very wet.
An area of low pressure will track along the I-70 corridor Tuesday and deliver widespread showers and heavy storms. Between now and Wednesday some areas will see another one to two inches or more. It’s already been a wet June as most cities have eclipsed the monthly average (4.25″ in Indianapolis) for rainfall already.
If you’re looking for relief from the muggy air I’m afraid to say we’re in the long haul… with mid to upper 80s the next 7 days and beyond. In fact long range indicators suggest a rather hot finish to June and beginning of July. Confidence is growing on a prolonged stretch of 90s heading into the 4th of July holiday. Stay tuned and have a great evening – Sean Ash
